The Firefox "New tab" page shows quick-navigation buttons. At the top right of each button, the 3-dot menu has an Edit option. On the edit dialog is a link "Use a custom image", which then prompts you for a image URL.
I've tried pointing this to images in my Google Photos (a 1024x1024 .JPG), using an open-shareable link, but it doesn't work.
a) What format does the icon image have to be in? b) Are there any limitations on the URL? c) Is there a way to use a locally stored icon image?
Any guidance would be most welcome! Thanks :)
